Run functions in parallel safely with typesafe parmap!

Features

Easy run different functions in parallel!

from typesafe_parmap import par_map_2
import time
from concurrent.futures import ThreadPoolExecutor

tp = ThreadPoolExecutor(5)

def long_running_int(param: int) -> int:
    time.sleep(5)  # long IO task here
    return 123

def long_running_str(param: str) -> str:
    time.sleep(5)  # long IO task here
    return "hello world"

int_result, str_result = par_map_2(
                        lambda: long_running_int(5),
                        lambda: long_running_str("test"),
                        executor=tp)
assert int_result == 123, str_result == "hello world"  # should finish in 5 seconds

Function return types are inferred correctly by mypy / pycharm!

reveal_type(int_result) # mypy infers int
reveal_type(str_result) # mypy infers str

Got more than two functions to run? We got you covered..

from typesafe_parmap import par_map_3

... all the way to par_map_22!
